The cooler box in my RRS, basically the same thing as the LR3 with different skin, does not come on with the key in the car and in the on position. However, with the truck off, key out and cooler switch in the on position, the cooler comes on randomly. Went out this morning and the box was cold, ice had built up on the inside and the cooler fan was coming on and off, perhaps because it triggered a too cold safety cutoff. Any ideas? On our LR3, the cooler box will only come on if the key is inserted and turned to the on position. It won't come on at all if the key is out of the truck. Thanks Phil
